Unable to get a stable setup

[pcaron]

So I've got a Macbook Pro 2018 and have been trying to get everything connected through this ThinkPad Dock...been messing with it for days, reinstalling all types of drivers and still cannot get the setup I want.

I've got ethernet, two USB devices, and two monitors (through DisplayPort and HDMI) on the latest version of Mojave Beta 6. Before today, I was running the latest 4.3 Beta 6 driver version and had 1 monitor connected successfully via AirPlay Display.

Connected a 2nd monitor today, which only mirrored my Macbook's screen, never showed up under Displays settings. Rebooted, and now both displays are black screens, neither show up in Displays, and AirPlay is literally not useable.

Upgrading to Mojave was probably a mistake and, unless I find a solution soon, I'll probably downgrade back to 10.13.6. If anyone has any ideas on current setup, that'd be awesome!

Thanks!
